I started my 88 cherokee the other morning, and the idle went to 2800rpm's. Waited five seconds and it came back down to normal. I tried this a few more times hoping for a fluke and it still happened again. I figured it was the IAC. The entire TB is cleaned including iac pintle and port. I unplugged the iac, took it out, pulled the pintle out (extended it) put it back in, leaving it unplugged and it idles fine now. But if i plug the connector back in, it will start revving funny again.
By the way...88 cherokee 4.0 AW4 RENIX. Any help is great. I would like to know this for sure before i spend $44 on a new one. Thanks.
